Scheduling of Independent Dedicated Multiprocessor Tasks

We study the on-line version of the well known problem of scheduling a set of $n$ independent multiprocessor tasks with prespecified processor allocations on a set of identical processors in order to minimize the makespan. Recently, it has been proven that even in the off-line case with unit…

Energy Dissipation measures in Three-Dimensional Porous Media

Transmission conditions obtained by homogenisation

Given a bounded open set in [Formula presented], [Formula presented], and a sequence [Formula presented] of compact sets converging to an [Formula presented]-dimensional manifold [Formula presented], we study the asymptotic behaviour of the solutions to some minimum problems for integral…

ICF-specific DNMT3B dysfunction interferes with intragenic regulation of mRNA transcription and alternative splicing.

Hypomorphic mutations in DNA-methyltransferase DNMT3B cause majority of the rare disorder Immunodeficiency, Centromere instability and Facial anomalies syndrome cases (ICF1). By unspecified mechanisms, mutant-DNMT3B interferes with lymphoid-specific pathways resulting in immune response defects.…

Intermittency in the velocity distribution of heavy particles in turbulence

The statistics of velocity differences between pairs of heavy inertial point particles suspended in an incompressible turbulent flow is studied and found to be extremely intermittent. The problem is particularly relevant to the estimation of the efficiency of collisions among heavy particles in…

Convergence of numerical schemes for viscosity solutions to integro-differential degenerate parabolic problems arising in financial theory

We study the numerical approximation of viscosity solutions for Parabolic Integro-Differential Equations (PIDE). Similar models arise in option pricing, to generalize the Black-Scholes equation, when the processes which generate the underlying stock returns may contain both a continuous part and…

Image Scaling by de la Vallée-Poussin Filtered Interpolation

We present a new image scaling method both for downscaling and upscaling, running with any scale factor or desired size. The resized image is achieved by sampling a bivariate polynomial which globally interpolates the data at the new scale. The method's particularities lay in both the sampling…

Fluidization and wall slip of soft glassy materials by controlled surface roughness

We present a comprehensive study of concentrated emulsions flowing in microfluidic channels, one wall of which is patterned with micron-size equally spaced grooves oriented perpendicularly to the flow direction. We find a scaling law describing the roughness-induced fluidization as a function of…
